ISC2 Certified in Cybersecurity (CC)Network SecurityEasy

A company is implementing a new security policy that requires all remote employees to securely access the corporate network as if they were physically present in the office. They need a solution that encrypts all traffic and provides a secure tunnel over the public internet. Which technology should they choose?

  1. ASMTP
  2. BHTTP/S
  3. CVPN
  4. DDNS
Show answer & explanation

Correct answer: C. VPN

A Virtual Private Network (VPN) creates a secure, encrypted tunnel over a public network (like the internet), allowing remote users to access internal resources as if they were directly connected to the corporate network.

Why the other options are wrong

  • A. SMTP is for sending email; it doesn't provide secure network access.
  • B. HTTP/S is for secure web browsing, not for full network access.
  • D. DNS translates domain names to IP addresses; it doesn't provide secure network access.

Virtual Private Network (VPN)

A technology that creates a secure, encrypted connection (tunnel) over a less secure network, such as the internet, allowing users to access private network resources remotely.

  • Encrypts network traffic.
  • Creates a secure tunnel.
  • Enables remote access to private networks.
  • Uses public internet infrastructure.

Memory trick: VPN is like a secret, private road for your data on the public internet highway.
